erations, and to deliver the milk or beverage of uniform mixture into acup or other receptacle in any quantities desired and in such po-Vsition that the receptacles are in convenient position to be easilyremoved. Y

Another object is to provide a dispensing outlet which is fixed to thecan so that it can be easily and conveniently cleaned and sterilized atthe same time as the can.

Another object is to provide a flexible or pliable valve closure whichis inserted in said outlet when the can is filled and is removed andthrown away when the can is emptied.

Another object is to provide a novel and simple device to agitate andlmix the liquidin the container to provide a uniform mixture vfordispensing. l

Another object is to provide an improved valve controlling mechanismwhich normally holds the outlet valve closed to prevent flowing ofliquid. 'from the container and which is operable to permit the valve toopen to dispense milk.

Other objects and important features are pointed out or implied in thefollowing details of description in connection with the accompanyingdrawing, in which:

Fig. 1 is a sectional side view showing the milk can in dispensingposition in an insulated cooling chamber which chamber is in an elevatedposition on a counter or stand of any suitable description so as to beconvenient for dispensing. It also shows the valve control mechanism,the section being along( the line I-I of Fig. 2.

Fig. 2 is a horizontal sectional view showing the floor of the coolingchamber and showing the outlet opening and the valve control mechamsm.

Fig. 3 is an enlarged diametric sectional view of the outlet ordispensing valve, showing the pliable valve closure in the open positionwith Vthrough the liquid in the said container.

the valve sealing .cap in place and .with a cams lower edge in positionto be moved rightward and thereby push the cap down from the valvedoutlet. I

.Fig. 4 is an enlarged diametric sectional view ofthe outlet valve inthe closed position with sealing cap removed.

Fig. 5 'is a horizontal sectional View substantially along the line 5 5of Fig. 3, the cam being shown 1in full lines-'in the position of Fig.3, and in lbroken lines in its rightward position.

Referring to the drawing in detail in which the similar referencenumerals refer to the similar parts in the several views, the inventionis described in detail as follows:

Air from the compressor l0 is forced through the air inlet valve li intothe container 2 and This action agitates the liquid and maintains auniform mixture. The compressor l0 is actuated either by an electricmotor, a solenoid or any other appropriate and suitable mechanical ormanual means. The compressor shown is manually operated by means ofthehandle I2. The rubber airV inletl valve 4 is removable so that a new onemay be used each time after the container is cleaned and sterilized.

The rubber sleeve 5 is placed between the oor .of the cooling chamberland the container 2 so thatthe air from the compressor l0 which isforced through the tube I6 will have to pass through the air inlet valve4a and. into the said container 2. 6 is an annular memberV for locatingthe Vrubber sleeve 5 in its proper position.

The bottom of the chamber Vl has a dispensing opening la therethrough,and adjacent to this opening is a vertical bearing lb. The liquidAcontainer 2 is normally inthe chamber l and has its dispensing outlet 3directly over the opening la and normally .closed by pressure of apusher I against the compressible valve-closure 3a. 'I'he pusher 'I isunited with a pivot 8 that is journaled in the bearing Ib and has armsextending laterally therefrom, one of these arms having an element 9thereon in the Yproper relation to be pressed by a receptacle R when thelatter is pushed under said dispensing opening; and such pressureagainst element 9 causes the pivot 8 to turn far enough to retract thepusher l and permit the resilient lvalve 3a to open for dispensing theliquid in the receptacle R.. The other arm on the pivot 8 is seen at Il,and it has a retractile spring I3 connected thereto for returning thevalve-control means Il-B-S-l to the normal valve-closing position.

To dispense the liquid from` the container,

a glass or other open top receptacle is pressed i against the concavemember 9 of the valve control mechanism, thus turning the mechanismVthrough the said outlet valve closure from; the The coilfs'pring I3, v.

container into the glass. which is attached to the arm` I1, normallyholds the vvalve control mechanism in thevalvef'closing position withsuicient pressure to squeeze the valve closure 3a shut, so as to preventthe now of liquid from the container. The valve closure 3a is merely ashort tube made'of some pliable andresilient material, such asrubber.The [valvefcasing and valve-.closure3a consti:- tute the dispensingvalve, Y

The rod I9 passes through the apertured end of arm II and has anabutment I9a on its free end. The said rod I9 is pivotally fastenedtothe door of the cooling chamber, and when thedoor is opened, the rodI9 pulls the arm Il and thus takes the prong 'I out of engagement 4withtheeoutlet valve closure 3a. The `container can then be removed andreplaced. When the door is closedthe spring I3 returns the mechanism toits closed position ready for dispensing.

What we claim as our invention is:

1. In a liquid dispenser, the combination of a liquid container having adispensing valve `at its lower end, a chamber having a door and having afloor provided with an opening over which said dispensing valve normallyrests in proper position to deliver liquid from said container to anopen-top receptacle, a valve-control means operable by pressure of saidopen-top receptacle vthereagainst so as to effect the flow of liquidthrough said dispensing valve into said recep- Vtacle while saidpressureis maintained, said valve to cause the flow of said liquid to cease`outlet provided with a valve, a' sealingy unit `adaptedto be secured`to and removed from said outlet,` and means, operatively connected withsaid door foreiecting removal of said sealing When the door l5 is beingVclosed, after.A the n container and its liquid contents. are placed inthe chamber I, the` lower inclined edge (see Fig. 3) of the cam orwedge-like element 20 slides over andupon the upper edge of the clos:

ing cap 3b, from the kfullfline position to theV broken line position ofFig. 5; and this elementv that the glass or, receptacle will be visiblewhile being I illed without undue bendingor stooping.
